Available in PDF, EPUB and Kindle. Book excerpt: The ignition of condensed substances is a recent scientific trend in combustion and explosion physics. Its principal results have been obtained largely by using computers and modern experimental techniques. In this book the authors present a comprehensive theoretical examination of various ignition models and the elaboration of experimental approaches for their description. The first three chapters were originally published in 1984 in Russian (V.N. Vilyunov, Ignition Theory of Condensed Substance, Nauka, Novosibirsk). For this English edition they have been revised and supplemented by new material. Two completely new chapters have also been added: one devoted to experimental studies and the other to local ignition problems. The book is the result of several years of active experience in the field of ignition. It will be of particular interest to research workers in chemical physics and to engineers dealing with the problems of fire-explosion accident prevention.

This book was released on 1983 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: The important problem of spontaneous ignition of solids heated by temporarily variant thermal radiant exposure is studied. Available data are examined in the light of a simple heat balance analysis to find that the observed behavior is predictable. An exposition of the elements of this general problem of ignition is made to realize that further research is required to predict the ignition behavior of realistic solids under realistic reradiative and free convective loss conditions.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study is to develop a fire-testing method that relates material ignitability and flame spread in the creeping mode. The analytical approach involves parameters and solutions arising from transient heat condition to a semi-infinite solid. Experimental data are generated on an apparatus employing a radiant panel to provide a varying heat flux to test specimens. Flame-spread rates and ignition events are measured against incident radiation and exposure time. The flame-spread data for given materials are correlated for varying exposure conditions by plotting the inverse square root of the flame-spread velocity against a product of the heat flux and a time function. The test and analysis results are shown for six diverse materials representative of aircraft (interior panels, carpeting, and seat cushions) and buildings (plywood, polymethyl methacrylate, and rigid foam).

Download or read book Analysis of Ignition of a Porous Energetic Material written by and published by . This book was released on 1998 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: A theory of ignition is presented to analyze the effect of porosity on the time to ignition of a semi-infinite porous energetic solid subjected to a constant energy flux. An asymptotic perturbation analysis, based on the smallness of the gas-to-solid density ratio and the largeness of the activation energy, is utilized to describe the inert and transition stages leading to thermal runaway. As in the classical study of a nonporous solid, the transition stage consists of three spatial regions in the limit of large activation energy: a thin reactive-diffusive layer adjacent to the exposed surface of the material where chemical effects are first felt, a somewhat thicker transient-diffusive zone, and finally an inert region where the temperature field is still governed solely by conductive heat transfer. Solutions in each region are constructed at each order with respect to the density-ratio parameter and matched to one another using asymptotic matching principles. It is found that the effects of porosity provide a leading-order reduction in the time to ignition relative to that for the nonporous problem, arising from the reduced amount of solid material that must be heated and the difference in thermal conductivities of the solid and gaseous phases. A positive correction to the leading-order ignition-delay time, however, is provided by the convective flow of gas out of the solid, which stems from the effects of thermal expansion and removes energy from the system. The latter phenomenon is absent from the corresponding calculation for the nonporous problem and produces a number of modifications at the next order in the analysis arising from the relative transport effects associated with the gas flow.
